Heavy contaminated soil cleaning and recovery system

In the past decants, economic development is the main concern of most countries and governments. It generates huge quantity of pollutions and wastes. One kind of waste is the polluted soil. Especially the heavy contaminated soil generated from chemical industry and drilling rig and oil field. The contaminated soil contents different kinds of waste oil, heavy oil, lubrication oil, diesel oil, grease oil, chemicals and other kinds of waste materials.
The drilling waste can be stocked in the waste pit or collected by trucks or vacuum truck, and dumped near the site work for treatment.
The contaminated soil material can be dumped by using bracket loader to the newly supplied pump feeders or screw conveyer to the treating system for cleaning and separation.


And then the contaminated soil material can be then transported via a belt conveyer or screw conveyor or other kind of transfer device to cleaning tank. Hot water will be added to the tank, to mix and heat in the washing tank. The cleaning tank is a tank with mud agitator and transfer pump, and with the function of mixing and heating. The mixing tank heating tank can be a vertical tank on Horizontal tank.
The mixed heated material are mixed with water and chemical and pumped from the Mix and heat washing tank to Soil Process Tank. In this step, shale shaker can be use to separate solid from liquid.
Centrifuge separation system will be followed after shale shaker separation. Chemicals should be added to the centrifuge for a better separation. Most of fine soil can be moved in this step. With chemical dosing, some of the fine soil smaller than 2 ~ 5 microns can be removed.
The liquid mixture from centrifuge separation will be moved to 3-phase separation system to separate soil, waste and oil. The recovered water can be reused in this heavy contaminated soil treatment system as dilution and heating water. While the recovered oil can be sell to the oil treatment factories.

Applications of mud cleaner in solids control system

Mud cleaner is popular equipment for mud solids control and drilling fluids recycling. A mud cleaner is a combination of desander separator and / or desilter separators mounted over a solids control shale shaker. Compared with solids control shale shaker, mud cleaner will be mounted with fine mesh screener. Mud cleaner normally use shaker screen over API 100.

Drilling fluids is fed to the inlet of the hydrocyclone (desander and/or desilter) to separate particles, and the underflow passes to the fine screen mesh, while the particles larger than screen opening size will be discarded and removed from the solids control mud system.

In most drilling activities, a mud cleaner is installed in the solids control mud systems, with shale shakers, pumps, mixing system mud agitators, mud guns, etc… All the solids control equipment are mounted on mud tanks in the same drilling rig location, to work as a full functional system.
For some small non-oil and gas drilling rigs, like water well drilling rigs, piling rigs, HDD drilling rigs, etc…they only have a very simple request on the mud treatment. They do not use mud tanks, as an instead, they use mud pit rather than mud tank system. In this case, the complex drilling fluids cycling system is not necessary. Operators can only use shale shaker or mud cleaner, and choose suitable feeding pump per their job site conditions.

Types of mud cleaners:
1)    A mud cleaner can be a combination of desander hydraucyclones mounted over a shale shaker for 2 stages separation.
2)     A mud cleaner can be a combination of desilter hydraucyclones mounted over a shale shaker for 2 stages separation.
3)    A mud cleaner can be a combination of desander hydraucyclones and desilter hydraucyclones mounted over a shale shaker for 3 stages separation.

GN Solids Control designed mud cleaner can be used as a full set solids control shale shaker and a desander desilter unit, buy removing the hydraucyclone unit.

Operator perform checking of decanter centrifuge

Various industry that need delicate separation often consider decanter centrifuge due to its high RPM rotation speed.  Decanter centrifuge to be function it well, it needs to be well balanced on bowl that contain horizontal screw that perform the separation.

When decanter centrifuge is arrived to its location, the balance of the bowl should be first one to check for possible problems. When the transport personnel will be sent to the horizontal screw centrifuge, we must promptly carry out inspection, in order to prevent future disputes, we better be able to face the inspection, to confirm the quality of the horizontal screw.

When decanter centrifuge arrived,  it needs observe the appearance of opening the crate, and then observe the appearance of decanter centrifuge, check the external metal have no obvious cracks, scratches, occur in the process of handling without impacting the dent. Manufacture that provide the inspection list,  the receiver will check all the parts are available, the model and the purchase of the goods are in the same way, this can effectively avoid sending the wrong goods.

Connect the decanter centrifuge with power source and turn it on, examine some of the functions of the horizontal screw decanter centrifuge, if the use of the general function appear without issue during the inspection, then the decanter centrifuge is ready for treatment operation.

Manufacturer like GN Solids America LLC suggest below if driller facing during the process of the drilling fluid.  Regular maintenance on the centrifuge such as regularly  washing the inlet and outlet by filling water or diesel is major step to avoid serious breakdown.  It is also crucial that  add lubrications  to the bearing parts to ensure proper lubrication. In order to ensure the process in the use of these parts in regular drilling operation which influences the effective of oil well drilling. The electronic parts of the centrifuge are working the best by running certain period of time frame (like none-stop for hours) and  avoid rapidly turn on and off  of the decanter  centrifuge often can make sure less-failure of the parts as well.
